[Swift 16] SFE16-42 CPU at 95C for simple tasks, exhaust aimed directly at screen

edited January 16 in Swift and Spin Series

Is it normal for the Swift 16 to have its CPU jump to 95C doing simple tasks using only one core? Also, should I be concerned about the laptop's exhaust being aimed directly at the OLED screen while the laptop is opened? It doesn't sound good for an OLED screen to have a 95C laptop's exhaust aimed straight at it from less than an inch away.

    95C is high as a steady state unless the CPU is running full tilt. From the fan table they are expecting it to run steady state in the 40-60C range:

    With the fan ramping to full speed at 80C and dropping back off that speed again at 63C. The second fan has a different curve:

    it comes on at 95C and shuts back off at 75C. It sounds as if, perhaps, your CPU fan isn't running at all and the second fan is taking up all the slack. I'd contact Acer support and get a ticket open for repair, or swap the unit with your vendor if it's been a short enough time.

    Change power plan to Balanced and reset the power plan to factory defaults, reset BIOS to factory defaults (F9 in BIOS and save settings on exit), keep the power adapter plugged in 24/7. Vents under the screen do no harm to the OLED, all new Swift models have vents under the panel (passive and active cooling). If the CPU temp. still overheats bring the laptop to Acer Services in your country for checking.

    Just to add some further info for you, as it depends on the work that you do on your Swift 16 laptop, don’t just look at extreme instances with temps as average temps are the best way to gauge your cpu performance. Install HWiNFO64 and go to this software’s Sensor Status settingand look at your cpu temps that this software measures temps, as you will find that the 94C temp must have been monetary and not an average temp reading.

    Also, I don’t know the exact Swift 16 model and spec laptop that you have, but make sure that you have Win-11 20H2 installed and all the Intel and Nvidia drivers (if you have a dedicated gpu) and your Swift 16 latest bios installed, so that your laptop has all its drivers up to date, as that is what I’ve done on my Swift X SFX14-51G with its i7-1260P/RTX3050Ti/16GB DDR5-4800 ram spec laptop, that out of the box its cpu was overheating as its fans were going crazy too but doing all the updates has made this laptop perform allot better. Good luck and hope this helps you out further

    I'm sorry if it was not clear from my initial post, but these temperatures are not "extreme instances". It doesn't just shoot up to 95°C, it stays there until the task is done. For example while watching videos. Or when running the expectation maximisation algorithm on a gaussian model. Which is a really simple algorithm utilising only a single core. I kept the laptop entirely suspended in the air so airflow is free as can be, yet it sticks to 95°C for as long as the program runs. My model is the SFE16-42 (the one they advertise with a 1440p webcam while in reality it's only 1080p)

    It happens both on wall charger as well as battery, all on the balanced power profile. And the vents aren't under the screen, they're aimed right at the screen. Super hot air blown directly at the OLED. Who do I contact about this temperature issue?

    Unfortunately, that is how the design of this Swift Edge SFA16-41and SFE16-42 laptop is, its mind boggling why Acer decided to put those vents on top of the laptop to vent hot air onto this laptops screen? The only solution for you is to consult Acer Tech Support and talk to them about these issues of your Swift Edge SFA16-41 laptop and complain about those issues and get them to fix it, if they don't do anything about the heat and to change the cpu paste, then you need to open the laptop yourself or get a technician in your area to do so and open the laptop and you need to tell him to also put tape underneath those vents so that no hot air is projected onto the screen and use a laptop cooler when you use this laptop also, those are your only options. Good luck and hope this helps you out.

    Thanks for your answer :). I'm not sure taping the vents would be a good idea as there's no other place to put the air haha. I just wanna figure out whether 95°C on a fresh laptop running simple algorithms is normal. If it is, I'll replace the thermal paste myself, if not, I might need to have the laptop replaced. I'm not sure if replacing the thermal paste will void the warranty, so I gotta wait till I have an answer. And since customer service has not sent a single reply this year I decided to try on the forums.

    Thanks. I will try to open a support ticket as I bought directly through Acer. Though they have not answered a single email for over a month now, nor have they refunded my previous returned model yet.

    Wait, where is this second fan you are talking about? I can only see one through the vents on the back. Can I switch this topic to unanswered?

    Your SFE16-42 only has one fan, but it sets the fan speed based on two temperature sensors. I don't know which overrides the other, but I'd expect it to be the second one.

    Do you know if the heatsink/fan from the SFE16-43 fits the SFE16-42? I saw in some benchmarking tests it should only be 88°C running prime95, but mine is 95°C and throttling hard. Might be nice to have the dual fan setup to reduce it from 88°C to better temperatures.

    The mounting holes for the two different heat sinks are completely different, so no, it will not work.
